New Gamma Radiation Proof RFID tags launched by SMART TRAC

Amsterdam: SMARTRAC N.V has announced the launch of a RFID transponder that withstands gamma radiation of up to 45 kilogray (kGy). The new transponder is best suited for medical applications where aseptic conditions are mandatory. There are many benefits of sanitizing medical equipments with gamma rays. The radiation destroys the DNA of any micro organisms present in the equipments. Radiation sterilization is the only process in which products can be sanitized including their packaging, as the gamma rays permeate materials and casings such as metal containers easily and without any appreciable increase in temperature. Irradiation thus becomes a faster, easier and effective method compared to heat and chemical sterilization. Plus it is environmental friendly. The new transponder has been developed based on the company’s S-Tag product family. SMARTRAC S-Tags comply with the ISO/IEC 15693 standard. The new S-Tag comes at a size of 16mm and with a Fujitsu FRAM chip. The chip provides low power consumption, high-speed writing, long data retention and good communication performance. The data does not get affected by the radiation sterilization process due to the chip’s ferroelectric characteristics. Additionally, optional customer-specific laser engraving of identification numbers on the tag is included. This removes the need to use additional stickers and barcodes. Other fields where the S-Tag has application are aerospace, plant breeding, food irradiation and laundry.
